-----------------------------------------
Summary: Web Socket not updating notebook content correctly
Key: ZEPPELIN-1492
URL: https://issues.apache.org/jira/browse/ZEPPELIN-1492
Project: Zeppelin
Issue Type: Bug
Environment: Google Chrome 53.0.2785.116 m
Zeppelin Version 0.6.1
Reporter: Aleksandar Buha
While accessing and editing the same notebook via two web-browser windows,
synchronization is failing if I do two consecutive updates from one of the
browser windows.
This issue can be reproduced with the following two browser-windows and a
single notebook.
Browser A:
%pyspark
print "Original Zeppelin Notebook"
In Browser B) edit the notebook and the above command to:
%pyspark
print "Notebook is updated...."
If I run the notebook via browser A followed by browser B, everything is
updated nicely. However, if I add the following line to the Notebook though
Browser B:
print "....once again"
and run the notebook through Browser B again, the content in Browser A is not
updated.
Inside WebSocket object (Browser A) I can see that "op":"NOTE" has attribute
"text":"%pyspark\nprint \"Notebook is updated....\"\nprint \"....once again\"".
Unfortunately, I do not see the second print statement displayed on screen.
